High-temperature-resistant concrete based on regenerated ceramic aggregate and preparation method of high-temperature-resistant concrete
The invention provides high-temperature-resistant concrete based on regenerated ceramic aggregate and a preparation method thereof, and the preparation method comprises the following steps: crushing and sieving waste ceramic to obtain regenerated ceramic fine aggregate; and using the regenerated ceramic fine aggregate to replace sand in the existing common concrete proportion, and mixing cement, sand, stone and the regenerated ceramic fine aggregate to obtain the high-temperature-resistant concrete. The mass substitution rate of the regenerated ceramic fine aggregate substitution sand is 50%-90%. By adopting the technical scheme of the invention, the sand is replaced by the fine aggregate prepared from the regenerated ceramic fine aggregate, so that the obtained concrete has a smaller slump value, higher compressive strength and elasticity modulus and excellent high-temperature resistance; and the crushing preparation process of the ceramic aggregate does not need excessive design, and the method can be implemented by utilizing the existing conditions in actual engineering, and is simple to operate and easy to control.
本发明提供了一种基于再生陶瓷骨料的耐高温混凝土及其制备方法，其制备方法包括如下步骤：对废弃陶瓷进行破碎过筛，得到再生陶瓷细骨料；采用再生陶瓷细骨料替代现有普通混凝土配比中的砂，将水泥、砂、石、再生陶瓷细骨料混合，得到耐高温混凝土；其中，所述再生陶瓷细骨料替代砂的质量替代率为50%~90%。采用本发明的技术方案，以再生陶瓷骨料制作的细骨料替代砂，得到的混凝土具有更小的塌落度值，更高的抗压强度、弹性模量，并具有优异的耐高温性能；对于陶瓷骨料的破碎制备过程无需过多设计，利用实际工程中现有条件即可实施，操作简单，容易控制。
